American Airlines Flight 24 from San Francisco to New York was grounded last night after a caller threatened to hijack the plane. Authorities now say the threat was "non-credible," though the "suspicious male" behind the scare has not been identified, notes CNN. After the call, the plane was taken to a remote location and passengers were interviewed and re-screened by security personnel, ABC finds.

It was a tense couple of hours for passengers: "We weren't sure there was somebody on the plane or if there was something in the plane, a bomb or something like that," one man says. A couple holding Pakistani passports was removed from the flight for questioning and quickly released, the AP reports.
